One of the waste products of a nuclear reactor is plutonium-239 (239Pu).

Question

 One of the waste products of a nuclear reactor is plutonium-239 (239Pu). This nucleus is radioactive and decays by splitting into a helium-4 nucleus and a uranium-235 nucleus (4He + 235U), the latter of which is also radioactive and will itself decay some time later. The energy emitted in the plutonium decay is 8.40 × 10-13 J and is entirely converted into the kinetic energy of the helium and uranium nuclei. The mass of the helium nucleus is 6.68 × 10-27 kg , while that of the uranium is 3.92 × 10-25 kg (note that the ratio of the masses is 4 to 235).
